A new body breakout after a hot-tub visit needs assessment before a body-makeup purchase.

Connect the timing and location

CDC describes hot-tub rash as an itchy, bumpy eruption, sometimes with pus-filled blisters around hair follicles. It usually starts a few days after using a poorly maintained hot tub and can be worse beneath a swimsuit. Mild cases often clear in days; seek care if the rash worsens or recurs. [1]

Confirm what needs treating

Folliculitis can resemble acne. A dermatologist can confirm the diagnosis; some cases need medicine. AAD suggests warm compresses for comfort: 15 to 20 minutes, three to four times daily. If shaving, plucking or waxing caused the infection, AAD advises stopping those activities for 30 days. That advice does not mean every post-swim rash has the same cause. [2]

Check the next swimming visit

After swimming, remove the suit, shower with soap and wash the suit. CDC advises checking hot-tub disinfectant and pH with test strips: chlorine at least 3 ppm, bromine 4 to 8 ppm and pH 7.0 to 7.8. Report out-of-range readings to the operator; above 10 ppm chlorine also warrants contacting them. [1]
